COOKING-STOVE.

Specification of Letters Patent No. 3,164., dated July 8, 1843.

To all whom it may concern:

Be it known that I, ALBERT D. HART, of Pittsfield, in the county ofBerkshire and Commonwealth of Massachusetts, have invented a new andImproved Cooking-Stove, called a Vanquisher, for the Use of Wood andCoal. I do hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the annexed drawings, making a part of this specification,in which- Figure I, is a perspective view. Figs. II and III arehorizontal sections; Fig. IV, a longitudinal elevation representing thesideof the fire place and end of the oven; Fig. V, a longitudinalelevation represent ing the end of the fire place and side of the oven.

A in the accompanying drawings, is the hearth, a circular plate, with asunken bottom a extending nearly across its center.

B is the fireplace in an oblong form or varying from that to acylindrical form with grates suitably adapted for the use of wood orcoal.

C is a circular plate nearly of the size of tltehearth covering the fireplace, near the edges of this plate, directly over the extreme ends ofthe fireplaceare openings 6, b, Fig. III, and has a sliding plate 6.Fig. III of suitable dimensions to shut one end and open the other, orto have both half way open. This sliding plate may be moved in any ofthe known ways for moving slides or dampers.

D is a rotary plate with or without friction rollers made fast within arecess or flue which raises directly over the before mentioned openingsin plate 0 and rests upon it. In this plate D as seen at cl (Z is theflue on its extreme circumference sufiiciently large to admit the heatand smoke from one boiler to the other, the boilers e, e, e, e, areplaced around its surface in connection with the recess or flue, fromthe top of which flue raises two small pipes F F, from opposite sides;on the top; of these pipes rests an elevated and movable oven G, with.an opening on the top at H, for the main pipe. See Figs. I, IIII and V.This plate D may be moved in any of the known ways for moving rotaryplates on'stoves.

The operation of this stove is as follows. First. The heat and smokepass from the fire place at its extreme ends through plate G into therecess or fiue in plate D and is divided into four equal parts, andpasses through small pipes to and around the oven and off on top at H.Second. Move'the sliding plate C, so as to close one opening, and havingthe other open, the heat and smoke separate and pass to the right andleft through small pipes and off as before, thereby throwing the heatupon one half of the circumference, or by turning a damper in one of thesmall pipes the heat and smoke will all pass through the other, thusheating but one fourth of the plate D. Third. Bring the small pipesdirectly over the fire, hav-. ing the sliding plate and dampers open,thus throwing all the heat directly to the ends and around the oven.

What I claim as my invenetion and desire to secure by Letters Patent, is
